Strange setup error

[mccormw]

All of the music was on the 412 was the folder Multimedia which is created by the setup process. It was synced from a newer 253be NAS which did not exhibit this issue. The version of HBS3 used was the one previous to the latest, which is 3.0.190812. I basically accepted the default except:
(I) it was scheduled to run after a bakup,
(II) NO filter was applied (this is the default), and
(III) 'Remove additional files in destination folder' and 'exclude duplicate files' were checked
